Slim chance is the objective way of expressing a low likelihood. Fat chance is a colloquial expression using irony. You say one thing but mean the opposite. It's more often used as just a quippy two-word reply.

Language doesn't make sense. When flammable and inflammable can mean the same thing, all bets are off. You cannot make sense of these things; you can only accept them.
